Summary/Abstract
This report examines a wide range of marine geoengineering techniques to remove carbon dioxide from the atmosphere and provides a comprehensive review of the international frameworks that govern these techniques. The report recommends (a) that a coordinated framework for proposing marine geoengineering activities, submitting supporting evidence and integrating independent expert assessment must be developed and (b) that a greater expertise on wider societal issues is sought with the aim to establish a knowledge base and provide a subsequent analysis of the major gaps in socio-economics and geopolitics.
